Abstract
A tester includes a housing containing a passive test circuit including a plurality of LEDs respectively connected to terminals of a multi-terminal connector jack on the housing for connecting the tester, by means of an associated cable harness, between a keyswitch module and other electronic circuits on an associated vehicle to be tested. Different harnesses may be provided, tailored to different vehicles. The test circuit is powered by a battery on board the vehicle and includes indicators dedicated to checking to see if the battery is connected properly and if an associated battery charging circuit on the vehicle is operating properly. The remaining indicators check different circuits, depending upon the particular vehicle being tested. The test circuit includes override switches associated with certain ones of the indicators and a test switch for simultaneously energizing all of the indicators. A relay shorts two of the jack terminals until the tester is powered, the cable harness including a diode across those terminals which is normally shorted out and is placed in circuit when the relay is energized.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
